三、近年來,環保署開始針對放流水中的氨氮訂定排放標準或是加嚴標準,今有 一污水廠將採用生物法處理水中氨氮，最後決議採用modified Ludzack- Ettinger(MLE)來去除水中的氨氮,請繪出MLE法的示意圖,並說明其理論 基礎(提示:硝化、脫硝)。(15%)

(1)試說明空氣品質指標(AQI)之意義。(7%)

(2)試列出兩種國內較常超出空氣品質標準之空氣污染物,並說明國內南、 北空氣品質之時空分布趨勢。(8%)

五、請說明典型自來水處理流程。在自來水處理廠完成處理程序後,水質都可達飲用標準,唯一較需注意的是「消毒副產物(disinfectionby-ProductsDBPs)」， 請問何謂消毒副產物?你會建議如何去除消毒副產物?(15%)

六、一靜電集塵器(EPS)用來處理流量為10000m3/min的廢氣,有效的漂移速度 (drift velocity)為6.0m/min此 EPS有98%的去除效率,請用 Deutsch equation 計算此EP的總收表面積(提示:In(0.02)=-3.912)。

七、請由空氣、水、廢物三大面向說明新冠肺炎(COVID-19)對環境帶來的衝擊。 (10%)

(a) At an instant after it passes B, the normal force exerted by the road on the car drop to one-third of the normal force at point A. Please determine the θ. (15%)

(b) If the car speed is variable, what is the minimum speed that will cause the car to lose contact with the road at the highest point C ? (10%)

(2) (Please see Fig. 2) Three identical small spheres, each of mass 1 kg, can slide freely on a horizontal frictionless surface. Spheres B and C are connected by a light rod and are at rest in the position shown when sphere B is struck squarely by sphere A which is moving to the right with a velocityVo= 2.4 m/s. Knowing that θ = 45°and that the velocities of spheres A and B immediately after the impact are and ， determine (a) (9%); and (b) the velocity of sphere C immediately after impact. (16%)

(3) (Please sce Fig. 3) The homogeneous sphere of mass m and radius r is projected along the incline of angleθ with an initial speed v0 and no angular velocity (ω0 = 0). If the coefficients of static and kinetic friction are μs and  μk, respectively, determine the time duration t of the period of slipping (10%). In addition, find the velocity v of the mass center G and the angular velocity ω at the end of the period of slipping.(7% and 8%, respectively)

(4) (Please see Fig. 4) As shown in Fig. 4, the crank AB rotates with a constant angular velocity of 600 rpm clockwise. Please determine: (1) the angular velocity of the connecting rod BD (10%); (2) the angular acceleration of the connecting rod BD (10%); (3) the acceleration of point D on the piston. (5%)
